8.6 Tunnel Interfaces

The ZyWALL/USG uses tunnel interfaces in Generic Routing Encapsulation (GRE), IPv6 in IPv4, and
6to4 tunnels.
GRE Tunneling
GRE tunnels encapsulate a wide variety of network layer protocol packet types inside IP tunnels. A
GRE tunnel serves as a virtual point-to-point link between the ZyWALL/USG and another router
over an IPv4 network. At the time of writing, the ZyWALL/USG only supports GRE tunneling in IPv4
networks.

DESCRIPTION
This button is available only when you enable budget control in this screen.
Click this button to reset the time and data budgets immediately. The count starts over
with the mobile broadband connection's full configured monthly time and data
budgets. This does not affect the normal monthly budget restart; so if you configured
the time and data budget counters to reset on the second day of the month and you
use this button on the first, the time and data budget counters will still reset on the
second.
Specify the actions the ZyWALL/USG takes when the time or data limit is exceeded.
Select None to not create a log, Log to create a log, or Log-alert to create an alert
log. If you select Log or Log-alert you can also select recurring every to have the
ZyWALL/USG send a log or alert for this event periodically. Specify how often (from 1
to 65535 minutes) to send the log or alert.
Select Allow to permit new mobile broadband connections or Disallow to drop/block
new mobile broadband connections.
Select Keep to maintain an existing mobile broadband connection or Drop to
disconnect it. You cannot set New connection to Allow and Current connection to
Drop at the same time.
If you set New connection to Disallow and Current connection to Keep, the
ZyWALL/USG allows you to transmit data using the current connection, but you cannot
build a new connection if the existing connection is disconnected.
Specify the actions the ZyWALL/USG takes when the specified percentage of time
budget or data limit is exceeded. Enter a number from 1 to 99 in the percentage fields.
If you change the value after you configure and enable budget control, the ZyWALL/
USG resets the statistics.
Select None to not create a log when the ZyWALL/USG takes this action, Log to create
a log, or Log-alert to create an alert log. If you select Log or Log-alert you can also
select recurring every to have the ZyWALL/USG send a log or alert for this event
periodically. Specify how often (from 1 to 65535 minutes) to send the log or alert.
Click OK to save your changes back to the ZyWALL/USG.
Click Cancel to exit this screen without saving.
